302 Supposed Connection of Volcanic Emanations 



July 26th, Torrents of rain, attended with lightning and thunder, fell at 

 Malta, and there, for the time of year, was considered a phenomenon. 



1831. January 2d*, Earthquake at Lago Negro, in the kingdom of 

 Naples ; houses. &c, damaged. 



March 2d, Earthquake at Dover ; felt also at Ramsgate, Margate, Folk- 

 stone. The tide flowed half an hour earlier than usual. The captain of 

 the Crusader told me that the day was fine and calm ; but that, without 

 any previous indication, a sea suddenly arose in mid-channel, and that it 

 ran so high that there was great danger : felt also at Calais, and down the 

 French coast. 



July, August, The formation of Graham Island, in the Mediterranean.

During the summer, Eruption of Bos Tepe, on the Caspian Sea. 



December, Vesuvius in eruption. 



1832. January, Earthquake in the Apennines, felt at Rome. The 

 eruption of Vesuvius ceased at that instant. Earthquake along the Rhine.

1833. January 4th, 5th, and 6th, Earthquakes in South Wales, felt at 

 Swansea, Neath, Llandovery, Fishguard ; also felt at Exeter, and in Ire- 

 land. Shocks very severe, attended by a moaning and rushing sound, and 

 great vibrations. 13th, Earthquake in Gothland, and at Dalarne, in 

 Sweden. At the end of the month the iron mine at Fahlun fell in. Sub- 

 terraneous noises, and the falling in of the mine continued till February. 



February 8th, till March 27th, almost daily, Earthquakes at St. Kitt's, 

 West Indies ; felt in Nevis and Antigua. Shocks more severe than ever 

 known. All the stores closed in consequence; the residents fled on board 

 ship for safety. So much mischief not done since 1797. The commotion 

 in Nevis so great as to have broken a great quantity of wine in the cellars 

 at Mount Pleasant. In one night, a friend writes me word, there were 

 twenty-four shocks.

N.B. During March and April (up to April 15.) the cholera ravaging

 1831, and 1832. They may form part of another communication. 



-j- It is observable that on August 1 1. a violent hurricane from the south- 

 west desolated Barbadoes and several other of the West India Islands, as 

 Dominica and St. Vincent; and that on August 17. a most frightful 

 storm passed over England, from the north-west to the south-east, being 

 attended by thunder and lightning : celebrated by the lo^s of the Rothsay 

 steamer. 



J Dr. Daubeny (Description of Volcanoes, p. 214 — 216.) has given a table 

 of correspondences between the eruptions of Vesuvius and Etna, to which 

 these and one or two other instances in the present list might be safely 

 added, especially the two violent eruptions April 27. and May 16. 1830.
